Abstract: A system for impedance matched switching of an input signal from an input source includes a first means, such as an FET, for controllably switching the input signal from an input terminal connected to the input source to an output terminal, the switching being controlled according to a control voltage. The system further includes a second means, such as an FET, for controllably switching a matching impedance between the input terminal and ground according to the control voltage. When the input signal is prevented from passing from the input terminal to the output terminal by the first means for controllably switching, the input signal passes through the matching impedance, which has an impedance characteristic substantially matched to an impedance characteristic of the input source.

Abstract: The present invention provides a system which uses a number of network nodes (2) which can communicate wire lessly with communications devices (3-8) coupled to the network. The network nodes are all connected to a network server (1) which can be used to provide additional services, such as Internet connection. The system uses at least a local short range radio connection for interconnecting the network nodes (2) to the communications device (3-8), thereby allowing the user of a communications device access to the network from anywhere within range of a suitable network node. This allows network nodes to be located throughout a building, such that a user can have access to the communications network at any location within the building.
